i Thisinvention relates torn'ew and useful improvements in sugar mills, and partienlariy to,v devices for sterilizing the juice troughs. .l l `When the sugarmillis stopped for a period of time,as forinstance, over night, la, scum, containing bacteria lcollects ony the walls kof the juice troughs, causing fermentation which will destroy or greatly retard the effects of the following steps in the process of treatingthe juices, s houldfreshjulces be permitted to flow into the' troughs: It is customary to scrape off this collection before the freshy juices are permitted to H ow into the troughs from the cane squeezlng rolls. Sometimes steam is injected into the troughs through the Amedium of a hose, but

this is dangerous to the operator, as the hose becomes very hot, and the steam often burns the operator. It is with these objectionable features in view that the present device has been made.

The principal ob'ect of the. invention. 1s to provide means or sterilizlng the juice troughs, by means of steam, so that the operation can be performed without danger to the operator, as well as to more perfectly cleanse the troughs with the result that the character of the resultant product is greatly im roved.

A urther object is to provide a knovel means for injecting the steam into the troughs so that all parts of the walls thereof will be attacked by the steam.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawings.

In the drawings Y Figure 1 is an elevation of a juice trough showing the invention applied thereto.

Figure 2 is a vertical transverse sectional view therethrough.

Figure 3 is a vertical longitudinal central sectional view.

Figure 4 is an elevation of a modification of the device.

Figure 5 is a vertical longitudinal central sectional view through the modification.

Referring particularly to the accompanying drawings, and especially to Figures 1, 2, and 3, 10 represents the juice trough which receives the juices squeezed from the cane by rollers (not shown), arranged thereabove, an outlet pipe 11 being connected to the bottom of the lower end of the trough Afor, ycarryingjof the juices to suitable receptacles, no t' shown. Mounted 'on the, vertical wall of the lower end of the troughgis a depending plate 12,., and fitted in anl opening'inthis plate is v,an -ape-rturedy boss.;13,

whichprojects through anropening 14 ,iin

. theend of the trough. Secured tothe lower end o f this plate 12, andcurvingupwardly .and outwardly therefrom, is an armk 15the upper endV of which is; formed withga separableA bearing ,box 16, in which is supported ,the pipe 17. Connectedv to this pipe, at the 'outer end thereof, is a steam conduit 18, which lleads t0 a Asource of steam supply, and in this pipe Mounted on thel inner end of the pipe 17 isa steam turbine 20, of suitable size and design, and' connected with the other side of the turbine is a pipe 21, which extends is la control valve 19.

through the before-mentioned boss 13, and

longitudinally within the trough 10, the other end of the pipe being rotatably supported in the bearing 22 mounted on the bottom of the trough. Throughout the length of the pipe 21 are steam outlet openings 23, from which issues the steam for the purpose of cleansing thewalls and bottom of the trough.

Steam is introduced into the pipey 17, and Hows into the pipe 21, to finally issue from the openings 23 against the walls of the trough.

The steam which enters the pipe 17 causes` the turbine to rotate, with the result that the pipe 21 is rotated, the steam which eX* hausts from the turbine escaping through the openings 23 against the walls of the trough. It will thus be seen that as the pipe 2l rotates, the steam whichv is constantly issuing from the openings 23, will attack every portion of the walls of the trough, with the result that the trough will be perfectly sterilized and ready for use again. Furthermore, this obviates the usual laborious and dangerous methods now practiced. .It will, of course, be understood that the condensed steam, and the detached scum or collection removed from the walls of the trough, escape through the outlet pipe 11.

Referring particularly' to Figures 4 and 5, 24 represents the juice trough which lhas the plate 25 secured to one end, and on the lower end of said plate there is'secured-the A suitable packing gland 29 is mounted on the adjacent end of the pipe 28, and connected in this gland is one end of a perforated pipe 30 which extends through the apertured boss 3l, Jformed in the plate 25,

I lVhile I have shown two methods of rotating the ste-amy pipe Withinthe trough, I doY not Wish'to be conned to `either form, as I may use either, or both, or some other method equally as eective. rIhe principal feature* of the present invention resides in the provision of a perforated pipe located Within a juice trough in position to receive steam from any 'suitable source, and to pro ject the steam againstv the Walls of' the trough, when the pipe yis rotated, thus more Y ing said pipe thoroughly cleansing the trough than With devices used heretofore.

Vvvhat is claimed is l. The combination With the juice trough ci a sugar mill, of a bracket mounted eX- teriorly of the trough, a bracket mounted interiorly of the trough, a rotatable perforated steam pipe' supported at its ends in said brackets, and a steam motor for rotatand discharging steam thereinto.` f Y 2. The combination with the juice trough o'l a sugar mill, of a perforated pipe ,dis-

lposed longitudinally Within the trough and having one end extending therefrom, and a steam operated motory operatively connected With the pipefor rotatingthe latter and arranged to dischargeits exhaust steam into said pipe.

In testimony whereof, I ailix my signature.y
